This, handed down in regular succession by the royal sages, was known. This Yoga, however, has been lost here over time, O Parantapa (burner of the foes).

Swami Sivananda

The king-sages knew this yoga, which was received in regular succession. That yoga, O destroyer of foes, is now lost due to a long lapse of time.

Swami Gambirananda

Follows the commentary of Shankara (Advaita).

Thus handed down in succession, the royal sages knew this (Karma Yoga). But with a long lapse of time, O Arjuna, that Yoga was lost to the world.

Swami Adidevananda

Follows the commentary of Ramanuja (Vishishtadvaita).

Thus, the regal sages knew this, which was received in regular succession. Over time, however, this Yoga has been lost, O scorcher of enemies!

Dr. S. Sankaranarayan

Follows the commentary of Abhinavagupta (Kashmir Shaivism).

The Divine Kings knew it, for it was their tradition; then, after a long time, it was at last forgotten.

Shri Purohit Swami

हे परंतप ! इस तरह परम्परासे प्राप्त इस कर्मयोग को राजर्षियोंने जाना। परन्तु बहुत समय बीत जानेके कारण वह योग इस मनुष्यलोकमें लुप्तप्राय हो गया।

Swami Ramsukhdas

इस प्रकार परम्परा से प्राप्त हुये इस योग को राजर्षियों ने जाना, (परन्तु) हे परन्तप ! वह योग बहुत काल (के अन्तराल) से यहाँ (इस लोक में) नष्टप्राय हो गया।
